The Mazda 787B was a prototype racing car built for 24 hours of Le Mans. It replaced the 767 and used a 4-rotor 26B Wankel engine which produced over 700hp.

The 787Bís 1991 win at Le Mans was historic as it marked the first victory for a Japanese manufacturer, and the first overall victory for a rotary engine powered car. The 787B was designed by Englishman Nigel Stroud.

The most famous 787B is the #55 car, painted in an outrageous bright orange and green scheme, sporting the logos of Renown and CHARGE. The #55 car led the 1991 24 Hours of Le Mans for three hours, from lap 320 to the finish, claiming the win. Drivers Johnny Herbert, Bertrand Gachot, and Volker Weidler completed 362 laps 4923.2 km, finishing 27.2 km ahead of the second-place car with an average speed of 205.3 km/h.

For a race car that with much pedigree, the people at Turn 10 Studios decided to bring the 787B into Forza Motorsport 4.
